Attention-deficit hyperactivity disorder, also known as ADHD, is a chronic condition that affects children, with symptoms often continuing into adulthood. Common symptoms of ADHD include inattentiveness, hyperactivity, and impulsive behavior. ADHD affects the behavior of children both at home and in school. 

According to the Federal Centers for Disease Control and Prevention, approximately eleven percent of children in the United States are diagnosed with ADHD. Boys are more commonly diagnosed with this condition than girls. Children with ADHD often struggle in school, have poor self-esteem and may be at an increased risk for drug and alcohol abuse as they get older. 

Research suggests 60–80% of adults with ADHD are never formally diagnosed. So, while about 6% of adults have ADHD, only a portion of them know it. With treatment, however, most people with ADHD can lead successful and productive lives.
